MAGAZIN E-WRAPPIN G MACHINE.

Application filed August 12, 1912, Serial No.

' To all whom it may concern:

known that I, DANIEL S. BAInn,of

of Toronto, in the Province of Canada, have invented certain newImprovements in Magazineof which the following Be it the city Ontario,and useful rapping Ma chines, is a specification.

This invention relates to mechanism for wrapping printed matter and thelike for distribution, and my object is to devise apparatus which willroll up with a magazine a sheet of paper drawn from a web and seal thesame.

I attain my object by means of apparatus which will grasp the magazine,and in some cases the wrapping paper, near the forward sides, and by arotary movement roll up the same together until the magazine iscompletely wrapped, the wrapper sheet torn from the web and edge pasteddown. firmly, and its accompanying drawings, in which F lgure l is avertical section of a portion device and its operating mechanism.

In the drawings like numerals of reference indicate corresponding partsin the different figures.

In this machine I employ certain feeding, cutting and pasting deviceswhich are well known in the art and need not be particularly described.Sufli of wrapping paper roller 2 and is fed forward by the feedingrollers'3 operated in 'anywell known manner.

I Specification of Letters Patent.

a previously gummed 8.

of magazines, to engage the ce it to say that a web are held in place attheir lower ends by the Patented Jan. 4, 191

714,687. Renewed September 1, 1915. Serial No. 48.579.

From the lower feed rollers 3 the paper passes between the guiding andfeeding rollers 4, as shown in Fig. The lower feed rollers 4 are gearedtogether, as shown at the left hand side of Fig. 2, by means of the spurgearing 5, so that they may be simultaneously operated in anywell-known. manner.

Intermediate the feed rollers 3 is placed construction. Paper cuttingdevices for partially severing the paper will be employed, intermediatethe, roller 1 and the pasting mechanism, but no claim is made for suchfeatures, as the present invention lies the pasting mechanism 6 of anywell known particularly in the means for actually performing thewrapping operations.

The magazines themselves are placed in a pile on th A slide 9 is adaptedplay backward and forward beneath the bottom of the pile magazines oneits edge 10. The result of its that the magaat a time to the by one withreciprocatingmovement is zines are fed forward one front of the table 7.This plate is actuated by means of the rock'arm 11 which is fulcrumedintermediate its ends. end of this rock arm is actuated by means of thepitman' 12 connected with a wrist pin on the gearwheel 14 suitablyjournaled on the frame and actuated by the gear wheel 39 on the shaft15.

he wrapping mechanism proper has as its basis the forks 16 formed on thespindles the bearings 18.

he forks are rotated through themedium of the pinions19 engaging thespindles 17 through the medium of suitable keys and keyways'. Thepinions mesh with the gear wheels 20 fast on the spindle 21 journaledin. the brackets 22. Th carry racks 24! These racks are dr ven bymeansof the cams 25 fast on theshaft 15, the lower ends of the racksbeing preferably provided with the anti-friction rollers 26. The rackslinks 27 said links being pivotally connected at their forward ends withthe racks and at I ese splndles also the pinions 23 which mesh with thetheir rearward ends with the frame of the normal.

A "curs some little distance back machine. The upper ends of the racksslide in) the brackets 22.

By the constructions just described the forks 16 are given a rotarymovement in one direction, the movement being then reversed and theforks returned to their original position. The forks'are also, asalready described, capable of endwise movement. This movement isimparted to'them at the proper time by the following mechanism: At eachside of the machine the rock arm 28 is fulcrumed intermediate its ends(see Figs. 4 and 2). The upper end of this rock arm is shaped like anordinary engage a. grooved hub 29 on the end of one. ofthe spindles 17The lower end of each rock arm engages one of'the cams 30 fast on theshaft 15 being provided with the antifriction roller 31 for thispurpose.

On reference particularly to Fig. 1, It will be seen that when amagazine 32 is in the position shown indotted lines that the frontedge'of the wrapping'paper lies on its upper surface adjacent theforwardside. The forks 16 have engaged between them the magazine at itsforward side, also in some cases the edge of the At this moment theforks are rotated rolling up together the magazine and the wrappingpaper until a complete cylindrical.roll is formed. j The web of wrappingpaper is partly cut or perforated at such intervals that rather morethan a complete turn of the wrappingpaper istaken around the rolledmagazine, after the latter has been completely rolled up The pasted orgummed edge of the wrapplng paper thus contacts with the wrapper, andthe-wrapper is thus secured about the roll. To insure a tight roll andthe proper pressing of the contactwiththe roll I provi e the pressurebars 33 preferably formed as rolls journaled in the blocks 34 movable toand from the forks 16 in the guides 35. -These pressure bars areyieldingly pressed toward the forks by means of the springs 36 engagingthe blocks 34 and the guides 35. The pressure bars thusmaintain a firmpressure on the roller as the wrapping proceeds while they readily yieldto accommodate the increasing diameter of the roll as wrapping proceeds.One important result follows from this increasing diameter of the roll.Thewrapping paper is by the rotating roll at a greater speed thanConsequently if it has been impressed with lines of weakness eitherbefore the web is placed inthe machine or as the paper is fed from theroll the part being about the roll is torn away from the rest "of theweb. This tearing away ocfrom the to insure also asted edge in clutchshifter to' wrapping pathemselves to drawn forward forks, so that at thetime the rolling is complete the now forward edge of the web is justapproaching the wrapping position shown in Fig. 1. Of course, the rapiddrawing away of the end of the web being wrapped round the magazine maybe assisted or entirely caused by rotating the forks 16 with. a surfacespeed somewhat higher than that of the paper feed.

The completely wrapped magazine is ejected by means of the followingmechanism: A kicker lever 37 is suitably fulcrumed at 54 on the frame ofthe machine with its upper end justbehind the position,

occupied by a completely rolled and wrapped magazine. At the properinstant this kicker lever is actuated to contact with the rear side ofthe wrapped magazine and throw the same forward out of the way of thesucceeding magazine. This movement is accomplished by means of the pin38 secured to the gear wheel 39 ,on' the shaft "15, which gear wheelforms part of the train actuating the magazine feed. A coil spring 40 issuitably arranged to retract the kicker as soon as its function has beenperformed. t should be mentioned that just before the kicker is actuatedthe forks 16 are being withdrawn from the wrapped magazine leaving thelatter free to be ejected.

The forks 16 being very short, andtwo being employed operating from eachend, the movement of engagement with and disengagement from the magazineis very much more rapidly performed than if a single fork were employedwhich would necessarily have to extend substantially from end to end ofthe forward side ofthe magazine necessitating a prolonged travel.

The use of two short forks, however, introduces a disadvantage whichspecial mechanism is required to overcome. That is, the magazine has atendency instead of rolling smoothly to buckleat the center between theforks, preventing the formation of a neat and well wrapped roll. Tocorrect this tendency I provide an anti-buckling device, comprising afinger 41, adapted to engage the upper surface of the magazine just backof the surface of an imaginary cylinder containing the forks. Thisfinger issecured to the spindle 42 journaled 0n the frame of themachine. The arm 43 is secured to the one end of the. end of the coilsprmg 44,-the other end of which is connected to a suitable stationarypart and tends At the proper moment straighten out a arm 46 which bymeans with a pin 47 the arm 43. The rock arm is actuated momentarily bymeans of the cam 48 on the shaft of one of the rollers 3. Just back ofthis finger the magazines pass under of the slot 55 engages lowingrestraining mechanism. One or more fingers 49 with bent ends 50 aresecured to a shaft journaled on the plate 8. A rock arm 51 is secured tothe shaft and has its upper end bent over the shaft of one of therollers 3 so as to be engaged by the cam 52 thereon, which bent end ismoved forward at the proper time by the cam to give a rearward kick tothe lower end of the said rock arm.

The result is that as each bottom magazine is fed forward the one nextabove is given a backward kick which effectually prevents it followingbeneath the bent spring tinge-r53. This isintended to keep back allmagazines except the bottom one but'as it must be more or less yieldingto suit inequalities in the binding of the magazines it is notsufiicient in itself without the addition of the positively operatedfingers 49, The next magazine above as it 49 forward sequently the rockarm 51 is position for its by the cam 52.

From the above description it will be seen that I have devised a machinewhich will descends pushes the fingers brought back in form a neat tightroll of'any magazine, or is particularly adapted 1 to magazines of someweight and thickness the like, and which which cannot be folded.
